Palindrome chain length in Python coming up incorrect

I feel like this should work correctly but I get an error with the count being 1 less than it should be.

def palindrome_chain_length(n):
count = 0
while str(n) != str(n)[::-1] :
n = n+n
count += 1
return count

Answer Source

If you just get count 1 less than you want, start with count = 1. And it seems to me that it should be:

n += int(str(n)[::-1]) 

instead of:

n = n + n 

(see comment @alfasin).
